[Python] Do I need to declare types? Documenting public class fields and enum values?

I would like to add API docs to my Python project. I've chosen the reStructuredText standard, as it is supported out of the box by PyCharm. Here are my questions:

1. 
   When describing function parameters (args) and the returned value, should I include their types? Even if they are already included in function signature? I.e.:
   
   # A1 - NO TYPES IN DOCSTRING
   def cuckoo(key: str, value: int) -> dict:
   """Do stuff.
   
   aram key: The precious key
   aram value: The valuable value
   :returns: The feedback wrapped in a dictionary
   """
   return {key: (value + 6) * 1024}
   
   
   # A2 - TYPES VIA :TYPE: AND :RTYPE:
   def cuckoo(key: str, value: int) -> dict:
   """Do stuff.
   
   aram key: The precious key
   :type key: str
   aram value: The valuable value
   :type value: int
   :returns: The feedback wrapped in a dictionary
   :rtype: dict
   """
   return {key: (value + 6) * 1024}
   
   
   # A3 - TYPES INSIDE ARAM: AND :RETURNS:
   def cuckoo(key: str, value: int) -> dict:
   """Do stuff.
   
   aram str key: The precious key
   aram int value: The valuable value
   :returns dict: The feedback wrapped in a dictionary
   """
   return {key: (value + 6) * 1024}
2. 
   How should I document public class fields? I've seen 2 conventions (the latter looking ugly and counter intuitive):
   
   # B1 - VIA CLASS PARAM
   @dataclass
   class Person:
   """Represents a physical person.
   
   aram id: Unique identifier
   aram first_name: Their first name
   aram last_name: Their current surname
   """
   id: int
   first_name: str
   last_name: str
   
   
   # B2 - VIA #:
   @dataclass
   class Person:
   """Represents a physical person."""
   #: Unique identifier
   id: int
   #: Their first name
   first_name: str
   #: Their current surname
   last_name: str
3. 
   Is this the correct way of documenting different Enum values?
   
   class MyStatus(Enum):
   """The final status of our operation."""
   
   SUCCESS = auto()
   """A great success!"""
   FAILURE = auto()
   """Something has gone terribly wrong."""
   TIMEOUT = auto()
   """It was taking too long, so we've decided to cancel the whole thing."""
